SPECIFICATION forming part of Letters Patent No. 666,646, dated January 29, 1-901. Application filed October 18, 1899. erial No. 733 ,964. (No model.)

To all whom it may concern.-

Be it known that I, ELLSWORTH H. BURTIS, a citizen of the United States, residing at Burlington, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Umbrellas, Parasols, and the Like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates more particularly to improvements in umbrellas, parasols, and other similar devices, in which the relation of the umbrella rod or stalk and umbrella-handle is such that it allows the stalk or rod carrying the umbrella-frame to rotate on its own axis.

The objects of my invention are, first, to enable the stalk or rod and umbrella parts carried thereon to freely rotate when force is exerted upon the said umbrella or umbrella rod or stalk from some extraneous source;

second, to permit the handle to be easily and securely attached. to and with facility detached from the umbrella rod or stalk without damage thereby to either the rod or stalk or umbrella-handle; third, to enable the lateral or end pressure of the umbrella rod or stalk to be exerted on and taken up by a sheath inserted in an umbrella-handle; fourth, to enable umbrella-handles and umbrella rods or stalks to be interchangeable; fifth, to increase the ease and facility with which the umbrella is carried when in use and to lessen the strain upon the arm and wrist of the person carrying the umbrella; sixth, to decrease the wear and strain upon the umbrella parts and increase the durability of umbrellas; seventh, to enable the parts having a rotary or detachable relation one with another to be readily and easily checked or brought in rigid or non-rotary relation and to well and securely connect umbrella rods or stalks and umbrella-handles, and also to be of such practical design that it will efiect other advantages and results, some of which may be referred to hereinafter in connection with the description of theworking parts.

The invention consists in the improved umbrella or parasol and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the clauses of the claim. I

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 illustrates the handle and a portion of the stalk or rod of an umbrella or parasol, said parts being in section and showing the connecting means. Fig. 2 is a side elevation showing the rod or stalk and its sheath and connecting means detached from the handle. Fig. 3 is a sectional detail on an enlarged scale, showing anattaching-nut or checking device arranged on the rod. Fig. 4 is a detail side elevatiompartly in section, showing a certain collar attached to the rod. Fig. 5 is a section taken on line 00 of Fig. 3, and Fig. 6 is a side elevation of the umbrella complete on a reduced scale.

In said drawings, represents the umbrella handle or grip; b, the umbrella rod orstalk c, a sheath inserted in said handle. Said sheath is of tubular or cylindrical form and is hollow, a straight socket to receive telescopically the said rod or stalk being formed so that said rod or stalk is held in axial alinement with said sheath, and no lateral movement, such as that common to a ball-and-socket joint, is permitted. (1 is the collar, arranged on and attached to said rod or stalk, and e the attaching-nut or checking device.

The grip or handle a is an ordinary handle,

of wood or other desirable material, with a recess or socket made in its lower end, substantially as shown, which recess or socket is formed to receive and hold that portion of the sheath which is above the shoulder a, formed by enlarging the sheath where it extends below and outside of the handle.

The sheath 0 is fastened within the recess loo rod or stalk, so that when said rod or stalk is arranged in operative relation to its sheath the said collar will be within the enlargement 0. as shown in Fig. l. The sheath is preferably constructed With the end within the handle closed and the other end open, the closed end providing interiorly an end-thrust bearing to be engaged by the extremity of the rod or stalk and on which the said rod or stalk rotates when not held in fixed relation by the attaching or checking nut, and said sheath is inserted and fastened into the handle, as above described. This sheath is preferably made of metal, although any suitable substance capable of offering sufficient resistance and a good hearing may be employed.

The collar 61 is securely attached to the umbrella rod or stalk b and forms a resistingshoulder thereon. This collar d is of such size and is so placed that when all the parts are properly assembled and the umbrella rod or stalk, with its collar, is inserted into the sheath the said collar will be incased in the enlarged portion of the sheath and will project endwise out of the said enlarged portion of the said sheath, so that it can present an abutment to the inner surface of the nut or 1 checking device efor the purpose of resistance or friction, by which means when the nut or checking device e is turned on the threaded enlargement a and thus is caused to press against the abutting end'of the collar, thev parts are clamped and held in rigid relation. 1 By this means I may efiectually prevent the I rotation of the umbrella rod or stalk on its own axis and also provide a desirable arf rangement of parts for maintaining a firm and controllable connection, between the um- By this same means I provide such an arrangement brella rod or stalk and the handle.

or device for attaching the handle to the umbrella rod or stalk that whenever desired the handle and rod or stalk may be disconnected without damage to either the handle or the rod or stalk.

The checking or looking nut or device is shown more clearly in Fig. 3. It is made to fit over the enlargement a of the sheath, attaching thereto preferably by means of the thread, as shown in the drawings.

On the interior end bearing 9 of the attaching-nut there are teeth 6 as shown in Fig. 5, of size and shape and relative location corresponding to the notches d in the abutment of the collar cl, as shown in Figs. 2 and 3. When-the checking nut or device 6 is screwed Mti'ghtly against its abutment, the corresponding teeth or notches fit more or less nicely and offer increased frictional resistance for the checking device, besides acting as stops to prevent rotation of the checking nut or device upon the threaded end of the sheath.

The collar d may be attached to the rod or stalk by means of a screw or pin or by brazing or in any manner that gives it stability on the rod.

The end of the rod, which may be conical,

as shown, lies in connection with the closed end 0 of the sheath, the latter affording the end bearing on which the umbrella rod or stalk may rotate.

The collar d isarranged a distance back from the extremity of the rod equal to the length of the small part of the sheath and so that when the rod is inserted in the said sheath the said collar will enter and lie in the enlarged chamber, diametrically fitting the sheath, so that the rotary movement within the sheath will be positive and without any material lateral movement or irregularity of motion, and thus when the attaching-nut is turned on the threaded end of the sheath so that the end bearing e no longer presses hard against the abutment d the rod 1) will be free to rot-ate within its sheath with a positive motion to effect the advantageous results before referred to.

The parts of my device are assembled as follows: The recessed or socketed handle is fitted with the sheath, the smaller end of said sheath being inserted i'nto the handle, so that the shoulder a is flush with the end of the umbrella-handle. The collar 01 is fastened to the umbrella rod or stalk, so that when the rod or stalk is inserted into the sheath the collar will be rotatably incased in the enlarged portion, as shown in Fig. l'. The checkingnut e is then screwed into position over the enlarged end of. the sheath, as shown. If it is then desired that the umbrella-rod shall rotate, the checking device or locking-nut shall be turned upon its thread till it is free from the abutting surface of the collar. The umbrella may be gripped by its handle and held in position for carrying when in use. Then the weight of the umbrella rod, frame, and covering will be carried by the incased end of the rod or stalk, and said rod or stalk, with frame and canopy, will be free to turn within the sheath or tubular handle-bearing. This rotation may be stopped at any desired instant by turning the checking nut or device upon the threaded sheath enlargement till it tightens against the abutting collar attached to the umbrella rod or stalk.

To detach the handle from the umbrella rod or stalk, it is only necessary to turn the checking and connecting nut 6 upon its thread till it is disengaged from theenlarged threaded portion of the sheath and then lift the handle from the end of the rod or stalk.

While I have described a construction preferred for the purposes of this application, it is obvious that various detailed modifications and Variations may be made from the exact construction shown to meet particular conditions without departing from the spirit or scope of this invention, and therefore I do not wish to be understood as limiting myself in described, having a handle with a tubular socket provided at its inner end with an endthrust bearing 0', a rod held therein against lateral movement, the said rod being permitted a positive rotation only in said socket when not held rigidly by the nut, and said nut adapted to hold said rod rigidly in said socket and to prevent longitudinal movement of the rod while the latter is rotating, substantially as set forth.

2. The improved umbrella or parasolherein described having a rotary rod provided with a collar and a handle having a socket provided with an end-thrust bearing for the rod at one end and at its opposite end, Where it projects out from the body of the handle having an enlargement to receive said collar, the said enlargement being threaded to receive a nut, and a nut having threads to be screwed upon the enlargement and adapted to engage the collar to prevent withdrawal of the rod, should the wind overcome the tendency of the rod to rest in rotary relation upon the end-thrust bearing, and adapted to fix said rod and handle in fixed relation, substantially as set forth.

in described having a handle provided with' I a threaded socket, a rotary rod having a collar with a toothed abutment at the end thereof opposite the extremity of the rod, the said extremity rotating on an end-thrust bearing within the socket, and a toothed and threaded nut, said parts being arranged and operating, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 14th day of October, 1899.
